Climate and Cryosphere (CliC): CliC encourages and promotes research into the cryosphere in order to improve understanding of the cryosphere and its interactions with the global climate system, and to enhance the ability to use parts of the cryosphere for detection of climate change.

Climate and Ocean Variability, Predictability and Change (CLIVAR): CLIVAR’s mission is to understand the dynamics, the interaction, and the predictability of the coupled ocean-atmosphere system. To this end it facilitates observations, analysis and predictions of changes in the Earth's climate system, enabling better understanding of climate variability, predictability and change.

Global Energy and Water Exchanges (GEWEX): GEWEX is an integrated program of research, observations, and science activities that focuses on the atmospheric, terrestrial, radiative, hydrological, coupled precesses, and interactions that determine the global and regional hydrological cycle, radiation and energy transitions and their involvement in global changes.
